Second one for me; with a little imagination one can see a planet. The first one? It looks like a stone and no more, if the background was completely black it would work better.
Reflection
Nice camera, would have liked the reflection to be stronger, the strap probably does get in the way abit spoiling the lines of the camera
The close up one for me it shows the texture better but there's nothing wrong with the first one both nail the theme
Definitely #2 - the detail almost has movement in it.. you can see how it has been formed.
Thanks all!
